The self-assembly design means a technician or shipping clerk can set up each box in seconds.

The MFL18144K is intended for packaging and shipping environments where document integrity is critical. The tuck-closure design eliminates the need for additional sealing supplies on the floor, making it practical for fast-paced shipping operations. Typical applications include mailing permits, engineering drawings, legal documents, blueprints, and other flat materials that cannot be folded. This product is equivalent to part number S-16928.
Equivalent to part number S-16928. Designed as a direct replacement for standard corrugated document mailer boxes of the same ECT-32-B construction and tuck-closure style.
No tools are required for assembly. Fold along the scored lines to form the box, insert the document, and close the front tuck flap firmly to secure the contents. Store flat mailers in a dry location to maintain board integrity before use. Do not overfill beyond the intended flat-document capacity, as overloading may compromise the tuck closure.
